1. Update Host1x-Syncpt - add syncpt-list in syncpoint-pool structure. - add exported "host1x-syncpt-*" interface and supporting private interface. 2. Update Host1x-NvHost - add support for nvhost-syncpt and nvhost-client interface and supporting private interface. - falcon and pm interface not supported 3. Update Host1x-Fence - add exported "host1x-fence-*" interface and supporting private interface. 4. Add Host1x-Poll - Per Pool polling workequeue created - add poll supporting private interface. 5. Add new IOCTL Jira HOSTX-5514 Change-Id: I187fa7ed89a3479e51b79f9d8d438ede75e1a36a Reviewed-on: https://git-master.nvidia.com/r/c/linux-nv-oot/+/3136834 Tested-by: Amitabh Dutta <amitabhd@nvidia.com> Reviewed-by: Bitan Biswas <bbiswas@nvidia.com> GVS: buildbot_gerritrpt <buildbot_gerritrpt@nvidia.com> Reviewed-by: Amitabh Dutta <amitabhd@nvidia.com>

/**

|
* TODO: Remove header after pre-silicon verification
|
|
* This header is required till emulation driver verification is done on Tho-r
|
|
* VDK platform. Since we are exporting new kernel symbol, header with declarion
|
|
* of modified symbols is required
|
|
*
|
|
* Changed cannot be added in orignal Host1x driver header files ("linux/nvhost.h"
|
|
* and "host1x-next.h") due to Host1x driver and other dependent drivers. Note in
|
|
* Tho-r verification config both the driver will co-exist.
|
|
*
|
|
* Some data structure are also re-delacred in this header for case where client
|
|
* driver wants to verify over emulation driver.
